Selection guides
Five practical comparisons for specifying EV charging and storage equipment - written from the buyer side, with the trade-offs stated plainly.
OCPP 1.6J vs OCPP 2.0.1
A practical comparison of OCPP 1.6J and OCPP 2.0.1 for charge point operators: what 2.0.1 adds, why the two are not backward compatible, and how to choose for a new build or an existing network.
CCS1 vs CCS2 vs GB/T vs CHAdeMO
Where CCS1, CCS2, GB/T and CHAdeMO are used, what power levels each typically serves, and how to specify a DC charger so it still fits the vehicle mix in five years.
7 kW vs 11 kW vs 22 kW AC wallbox
How to choose between 7 kW, 11 kW and 22 kW AC wallboxes: what the site supply, the vehicle onboard charger and the cable run each allow, and where the extra power makes no difference at all.
Air-cooled vs liquid-cooled DC charging
What changes when a DC charger moves from air to liquid cooling: cable weight, sustained current, noise, maintenance and total cost — and the point at which the upgrade starts to make sense.
LiFePO4 vs NMC for home storage
A buyer-oriented comparison of LiFePO4 and NMC home batteries: cycle life, safety behaviour, energy density, cold weather performance and what each means for the cost of stored energy.
